LED Incense Burner?

[Saijun]

Hello,

I'm currently re-building my altar, and I seem to be at a minor impasse; I'm unable to use real incense due to the size of our apartment (400sqft--one stick would make the whole place smell strongly), but I have seen at temples in the past a sort of LED incense burner; basically a light that looks like a stick of incense.

I can't seem to find one online; does anyone here know what I'm talking about or where I should look?

Metta and Gassho,

Saijun

EDIT: Something like this, but actually buy-able.
